A method of delivering an injectable to a joint region with a needle-free injection system having a chamber with a first end and a second end, an orifice of a pre-selected size in the first end, and a plunger mechanism for ejecting fluids from within the chamber, through the orifice, and onto a target site. When the chamber is filled with an injectable, the plunger mechanism is configured to eject a selected amount of the injectable onto the target site at a pre-determined rate. A skin site adjacent a joint is selected. The orifice is placed in an injection position relative to the skin site, whereby the skin site is the target site. The injectable is ejected onto the skin site with the plunger mechanism, whereby at least a portion of the injectable is delivered through the skin site to intradermal, subcutaneous, intramuscular, and/or intra-articular regions of the joint.
